Come to Virginia, where it's outright illegal for any establishment serving alcohol to not also serve food (and not only must food be served, it must account for at least 45% of revenue).
I'm nut sure I'd go that far... it's just I expect a "Pub" to include pub food.
Do they make you order food with every round of drinks? I remember hearing about places like that from my dad, and it seems it would have worked better in the era of cheap drinks/low built-in alcohol taxes.
